    The posterior circulation of the brain consists of the vertebrobasilar system and its branches. Vertebral arteries are responsible for about 30% of brain blood supply. The aim of this study was to examine the origin of the vertebral artery and to present the anatomic variations of the vertebral artery origin as well as the percentage of their appearance in the population. Material and methods: The origin of the vertebral artery was investigated in 30 patients; a total of 60 vertebral arteries were examined with CT angiography and DSA by Seldinger technique. Results: Abnormal origin of the vertebral artery was found in one (3.3%) patient. Vertebral artery originated directly from the aortic arch, as a second branch between left subclavian artery and left common carotid artery. Conclusion: Real abnormality of the origin of the vertebral artery is rare; in our series it was found in 3.3% of the cases. The described variations of the vertebral artery origin are not only interesting from the anatomical point of view, but they also find clinical applications in the surgery and diagnostic and therapeutic radiology.

    The aim of this study was to analyze the variable level of entrance into the transverse foramen and to point the risks of injury of the vertebral artery during accomplishing surgical procedures. For that purpose we examined 40 patients with CT angiography and analyzed the level of entrance into the transverse foramen. The vertebral artery entered the C6 transverse foramen in 38 (95%) patients. Abnormal level of vertebral artery entrance was observed in two (5%) patients, with entrance into the C4 and C5 transverse foramen. The incidence of abnormal level of entrance into the transverse foramen is relatively high, and this potentially dangerous condition should be detected on preoperative imaging in order to avoid vertebral artery injury.

    Anatomy and variations in the origin of the vertebral artery

    The vertebral artery (a. vertebralis, VA) is classically described as the first branch of the ipsilateral subclavian artery (a. subclavia), but multiple variations in the origin of that vessel have been reported in the literature. This examination was made on 110 unselected human hearts without pathoanatomical changes, obtained after autopsy of newborns, fixed in 10% formaldehyde. Standard anatomical methods, inspection and dissection were used for the analyzing of the origin of a. vertebralis. The analysis showed that 102 of the specimens (92.7%) had the usual pattern of the aortic arch and its branches, with the usual topographic relations. In three of the specimens (2.7%) a. vertebralis sinistra had a separate origin between a. carotis communis sinistra and a.subclavia sinistra. In one specimen a. vertebralis sinistra had a separate origin as the fourth branch between a. carotis communis sinistra and a. subclavia sinistra and there was a fifth branch originating distal to a. subclavia sinistra.

    The aim of this study was to analyze the tortuosity of the vertebral artery and to emphasize the clinical importance of tortuosity. The data derived from this study will add important contribution to our anatomical knowledge, but they will also find clinical applications in radiology and surgery. We examined 40 patients with CT angiography and analyzed the tortuosity of the vertebral artery. Of the vessels examined, 22 (55%) followed a relatively straight course from their origin to their entry into the transverse foramen. The other 18 (45%) patients showed some form of tortuosity. Both vertebral arteries showed high incidence of tortuosity. Our study has highlighted the possible role of vertebral artery tortuosity in diagnostic and surgical procedures in order to prevent vertebral artery injury.

    Anatomical features and clinical importance of the vertebral artery
    (2012-10-15)
    ;
    The vertebral artery and its branches are target of arteriographic investigations, ultrasound and Doppler visualization, MRI and CT imaging in many contemporary diagnostic procedures. The big horizon of procedures in the interventional and diagnostic radiology, orthopedic and surgery opens new avenues for the study of anatomy and especially variations of the vertebral artery and its branches. The aim of the present report is to give a summary of the vertebral artery anatomy as well as its variations, and to emphasize there clinical importance.
